Senior Backend Engineer

About the Role

We're hiring Senior Backend Engineers to own backend product development end-to-end from APIs and data models to the systems that orchestrate AI agents, run asynchronous workloads, and power knowledge retrieval.

Our backend is built with TypeScript/NestJS and Python, running on PostgreSQL and AWS. You'll work across both.

Experience: 8–10 years building production-grade backend systems.

What You'll Do
- Shape ambiguous product problems into technical designs. Work directly with product and design to pressure-test requirements, propose alternatives, and choose the simplest solution that actually solves the user's problem.
- Own backend features end-to-end — including API design, data modelling, implementation, rollout, and production operations. You ship it and you run it.
- Work across our AI and agent systems, including prompt and context design, tool execution, multi-provider LLM integrations, and streaming responses.
- Design and operate resilient asynchronous systems, including queues, retries, idempotency, cancellation,



observability, and fault tolerance. Our workloads are long-running and failure-prone by nature; correctness under partial failure is the job.
- Build ingestion pipelines that turn diverse content into structured, searchable, and retrievable knowledge.
- Build integration layers against third-party platforms, normalising inconsistent APIs, authentication models, and content formats behind reliable internal contracts.
- Design schemas and run live migrations against production data without downtime.
- Improve reliability, performance, and observability across production systems.

Must Have
- Strong production experience with Node.js and TypeScript, ideally with NestJS. Experience with Express or Fastify is also relevant.
- Strong production experience with Python, including asynchronous programming. Experience with FastAPI, Django, Flask, asyncio, Celery, or equivalent technologies.
- A track record of tak
